Is there a hard setting somewhere regarding the system RAM? I assumed
that rumprun would automatically detect the RAM configuration from
qemu correctly but I notice that the amount of RAM reported is
considerably less than the one configured in qemu command-line
options.
Notice below that 256 MB is configured in qemu, while just 123 MB is
reported in console log. Is there something which I am missing here?
command-line snippet:
------------------------------
rumprun "$virt" \
-I if,vioif,'-net tap,script=no,ifname=tap1' \
-W if,inet,static,"$ip/24","$gw" \
-e ERL_INETRC="$erlpath/erl_inetrc" \
-b images/erlang.iso,"$erlpath" \
-b examples/app.iso,"$erlapp_path" \
-M 256 \
-g '-serial file:/tmp/erlrun2-serial.log -nographic -vga none' \
...
console log:
----------------
